Gap junctions are cell-cell communication channels that consist of multimeric proteins called connexins.
Connexin 43 (Cx43) is the major component of gap junctions in the ventricular myocytes, and it is one of the important connexins in the atria.
Connexins (Cx) are recognized as structural constituents of gap-junctional intercellular communication (GJIC).
This is because the presence of connexins suppresses primary tumor growth," Dr.
7) Connexins and potassium channel proteins control key physiological processes in the heart and inner ear, demonstrating that similar electrically excitable tissues are present in both localizations (8) which are considered to be the regulators of autonomic response.
Connexins are transmembrane proteins that form intercellular channels important for cell communication and adhesion.
